The new Q2S30 Series of single-output DC/DC converters offer unprecedented density and performance in an industry-standard, quarter-brick footprint. Patent pending technology combined with state-of-the-art packaging techniques allows the Q2S30 to provide 30A of output current an 8.5mm package without a heatsink. The 100% surface mount design provides consistent high quality and reliability, and the SMT mounting option eliminates the need for separate (additional manual) operations to mount the converters to the motherboards during mass production.

Q2S30 Series � 30A Quarter-Brick DC/DC Converter 48, 24V Input 1.8V, 1.5V Output Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings may cause performance degradation, adversely effect long-term reliability, and cause permanent damage to the converter.

Overcurrent protection is non-latching with auto recovery. Vout can be increased to 10% via the sense leads to 10% via the trim function, however total output voltage trim from all sources should not exceed 10% of Vout (NOM) in order to ensure specified operation of over-voltage protection circuitry.
